I got this little funnel with my brand new SX20 w/ Merc 90hp. About eight inches long, neck about 3/4" diameter and a very narrow basin. It's labeled Envirofill manual fill aid. Anybody know what this is all about. Service dept didn't have a clue. Nothing in the owner's manual, but not much there anyway. Would include a picture but the smallest file I can create is still rejected.
